I have a table in a MySQL database V_Activity_SameTimeActivity with two fields SameTimeActivityId and ActivityId. They are both fields which reference the Id field from ACTIVITY_V table. I want to create a view that shows me the ACTIVITY_V.Name field for both sets of Id in the V_Activity_SameTimeActivity table. I can get one but not the other. This the query so far.
SELECT
ACTIVITY_V.Name AS MasterActivity,
V_Activity_SameTimeActivity.ActivityId,
V_Activity_SameTimeActivity.SameTimeActivityId
FROM V_Activity_SameTimeActivity
INNER JOIN ACTIVITY_V ON V_Activity_SameTimeActivity.ActivityId = ACTIVITY_V.Id;
I also want ACTIVITY_V.Name AS SametimeActivity to show with V_Activity_SameTimeActivity.SameTimeActivityId joined on ACTIVITY_V.Id
you can join again ACTIVITY_V
for your SameTimeActivityId
mapping
SELECT
t2.Name AS MasterActivity,
t3.Name AS SameActivityName,
t1.ActivityId,
t1.SameTimeActivityId
FROM V_Activity_SameTimeActivity t1
LEFT JOIN ACTIVITY_V t2 ON t1.ActivityId = t2.Id;
LEFT JOIN ACTIVITY_V t3 ON t3.ActivityId = t1.SameTimeActivityId;
